Article Influence
Definition
The average influence of a journal’s articles over the first five years after publication.
How It's Calculated
(0.01 * Eigenfactor score) ÷ X
X = 5-year journal article count divided by the 5-year article count from all journals
Article Influence is calculated by multiplying the Eigenfactor by 0.01 and dividing by the number of articles in the journal, normalized as a fraction of all articles in all publications. This measure is roughly analogous to the 5-Year Journal Impact Factor in that it is a ratio of a journal’s citation influence to the size of the journal’s article contribution over a period of five years.
How to Interpret It
The mean article influence for each article is 1.00. A score greater than 1.00 means each article in the journal has above-average influence. A score less than 1.00 means each article in the journal has below-average influence.
